■ Parameter setting
To allocate the override effective signal to the control input terminal, set (43) to the system para. If this signal is not allocated to the control
input terminal, this signal is deemed "always off."
Signal name Set value at system para.
Override effective 43
Override 1 44
Override 2 45
Override 4 46
Override 8 47

・Override scale factor
The scale factors while the override effective signal is on are as follows.
If “override effective” goes off, the 100% moving speed is obtained.
The signal not allocated to the control input terminal is deemed “always off.”

*Where override weighting is at initial value.
・Override weighting
Override weighting can be changed by using basic para. 17 to 20.
Basic parameter 17 to 20
Para. Name Setting range Initial value Change
17 Override 1 0 to 150% (in increments of 1) 10 Always
18 Override 2 0 to 150% (in increments of 1) 20 Always
19 Override 4 0 to 150% (in increments of 1) 40 Always
20 Override 8 0 to 150% (in increments of 1) 80 Always
When override 8, 4, 2 and 1 are all on, adding all initial values gives 150 (= 80 + 40 + 20 + 10). If the initial value has been changed and
resultant sum exceeded 150, the current speed is retained.
・Maximum speed
Maximum speed of the motor output shaft can be set by basic para.16 setting. However, this setting is invalid while pulse train input exists.
